FIREPROOF PAINT OR COATIN G OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 774,003, dated November 1, 1904.

Application filed May 31, 1904. Serial No. 210,354:- (No specimens.)

To all whom it may concern.-

Be it known that I, EDWARD R. S'rownLL, a citizen of the United States, residing at Portland, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Compositions of Matter for Fireproof Paint or Coating, of which the following is a specification. i

The object of the invention is to provide a tory nature for the protection of walls, bag walls, flues, caps, crowns, tire-boxes, and other similar constructions, and all surfaces exposed to the action of fire or heat in brick, tile, building-tile, pottery, and lime kilns, coke-ovens, glass pots and tanks, cupolas, and other build ings or constructions intended to Withstand a high degree of heat, also all surfaces and materials which it may be desirable to protect against heat or tire.

The paint of this invention is adapted to adhere to bricks, cement, stone, wood, iron, concrete, fabric, or plastered surfaces and is adapted to be sprayed thereon or applied with a brush in the same manner that paint of any i ordinary character is applied, or articles may be immersed or dipped thereinto.

The fireproof paint of the present invention is preferably composed of equal parts of finelypowdered carbid of silic n and seniiliquid waterlass and tnrte "to ten parts of calcium 1 carbonate in each one hundred parts, accord- Wonsistency desired. It is preferred to use soda waterlass, (silicate of sodium since its composition is ct ores-cent ant 'ciihances the drying properties of the paint, although otash waterlass (silicate of potassiiinilniay he used under some circii'ii'istances'.

l i E hen the carbid of silicon and silicate of sothe paint to efiervesce, which effervescence is overcome somewhat by the use of the calcium ca bonate. This effervescence takes place shortly after the paint is mixed, but does not impair the efi'ect of the paint if it is applied shortly after mixing. For this reason in cases where it is possible to apply a paint immedidiuni are mixed, gas is formed, which causes I l I paint result;

ately after mixing it is not necessary to add the calcium carbonate, the object of which,

as above stated, is to prevent eifervescence. 5

For use the paint is prepared in the following manner: For a gallon of paint pour into a vessel one-half gallon of s i licate-of-sodium fluid and then add in small quafi'ti ties tlifcafif bidgf silicon stirring briskly until a thick Slight variations in these proportions Will not destroy the quality of the paint. After mixing the two chemicais above specified the calcium carbonate may be added where it is dramatists prevent eifervescence. Where the. paint is applied as a protection to brick, tile, or pottery kilns, the ware placed and treated therein can be burned with less time and fuel.

It will be seen that the composition of the present invention is simple and inexpensive in formation and that it can be used under all circumstances in which it is desirable to render the parts impervious to heat. 7

What I claim as new, and desire to secure by Letters Patent, is

1. A fireproof composition consisting of carbid of silicon and water-glass mixed together, substantially as described.

2. A fireproof composition consisting of carbid of silicon and silicate of sodium mixed together, substantially as described.

3. A fireproof composition consisting of substantially equal parts of carbid of silicon and silicate of sodium mixed together, substantially as described.

4. A fireproof composition, consisting of substantially equal parts of carbid of silicon and silicate of sodium with calcium carbonate 8 5 added thereto, substantially as described.

5. A fireproof composition consisting of finely-powdered carbid of silicon, semiliquid silicate of sodium and from three to ten parts of calcium carbonate in one hundred parts of the composition, substantially as described.

6. A fireproof composition consisting of equal parts of finely-powdered carbid of silicon, and semiliquid silicate of sodium, and

from the above description 5 from three to ten parts of calcium carbonate carbid of silicon and silicate of sodium with in one hundred parts of the composition, subcalcium carbonate added thereto, substan- 1O stantially as described. tially as described.

7. A fireproof composition consisting of 5 carbid of silicon and Water-glass with calcium 1 EDWARD STOVVELL carbonate added thereto, substantially as de- Witnesses: scribed. G. W. HAYNES,
